This certainly is a case where generating an XSLT stylesheet (or modifying
parts of a stylesheet) is often a useful approach. A stylesheet is just an
XML document, so it's not essentially different from any other
transformation: if you know how to write XSLT, it shouldn't be difficult to
write XSLT that generates XSLT. One thing that makes it a little bit easier
is xsl:namespace-alias.
